The 2/5 body is the whole argument. Anthem effects that fire on attack usually ride fragile creatures priced to enable one alpha strike and then fold to the return swing; this one is built to survive both directions. Ward taxes the removal that would answer it, and the toughness lets it hold the line while still commanding the team the turn you commit forward. That combination eases a familiar strain in white aggro: the payoff that dies to the first blocker or removal spell it was meant to fight through. Because the pump keys off attacking rather than an activated ability, it costs no mana on the turn it matters, and the +1/+1 reaches every creature you control, so anything you do send in swings a size larger than the board looked a moment earlier. The design leans on a structural quirk of anthem-on-attack: the buff resolves in the declare-attackers step, sizing up your side before blocks are declared and punishing an opponent who kept a blocker home expecting the old numbers. The pump expires with the turn, though, so it does nothing on the opponent's crackback; the durability on defense comes entirely from the printed toughness and the ward tax, not from the swing. What lands is a five-drop team-pumper that shrugs off spot removal about as well as it enables a beatdown, which is an odd and welcome place for the archetype to stand.
